利用钛铁矿制备纳米钛基功能材料
Synthesis of titanium-based nanostructures from ilmenite
摘要
Abstract
It was found that a new method could be good for producing high quality titanium based nanomaterials to effectively control its morphology, structure and cost. Ball milling and acid solution treatment of natural ilmenite result in the products of TiO2nanorods.The lengths, width and thickness of the nanorods are 50−100, 5−20 and 2−5 nm, respectively. The results show that the nanorods exhibit a good electrochemical performance when they are used as an anode material for the lithium-ion batteries. A method which includes ball milling, annealing and acid leaching to obtain porous TiO2 from ilmenite has been demonstrated. The porous products show a bimodal pore size distribution. The typical range of big pores (50−80 nm) is attributed to the spaces between nanoparticles in aggregates, and the typical range centered at 3−20 nm corresponds to holes within nanoparticles. The obtained porous TiO2 shows an excellent photocatalytic activity.关键词
